Homemade fungicides | John Dromgoole | Central Texas Gardener

December 4, 2019

Hello gardening friends! Welcome to
Backyard Basics, I’m John Brown well I’m in the kitchen right now kinda there’s a lot of things that we can do
at home to work as a fungicide on our plants. We begin to see fungal problems. And let me show you what one looks
like actually. This is a rose. This is not uncommon to see on a rose. Right in here we see the beginning of the disease. See that black spot? That’s going to be pretty yellow pretty
soon. And it has spores that will spread all
over the plant. Here it is becoming yellow. See? The
spores will get everywhere. It will continue to be a problem. One of the things to do is to go ahead
and remove as many of these leaves as possible. That will help stop the spores from
spreading everywhere. There’s other things to do. One of
them is to mulch the soil. Pick up the fallen leaves and go ahead mulch the soil
underneath that because some of the sports are there too. So that would prevent the spores from
returning to the plant. You know what’s very useful on many of
these types of plants is a little bit of aspirin. The aspirin is a source of acetylsalicylic acid which builds up resistance in the plants. I think that maybe every two to three
weeks that would be a very good thing to do. In the kitchen you’ll find some baking soda and that’s a good fungicide. Why not go ahead and use the one that’s in the refrigerator already
instead of opening a new one. That will work just as well. So you’ll
take one big tablespoon of the baking soda, and then a teaspoon of vegetable oil, or a little bit about mild soap of some
kind, thoroughly mix these ingredients and keep it real agitated so it blends
well. You know you can see on the natural
gardener website this information also. And this controls black spot, white
powdery mildew, brown patch, and other fungal problems.
Another one of the classic products used to control fungal diseases is garlic. This is a well-known one from the past.
What you do is you use the different cloves, we’ll take them
apart, and you’ll smash them up really well, and then you’ll use the whole bulb in
doing this, not just the cloves, but the whole bulb will do it. And then you put that in the water and let it soak for a while. Give it
a good soaking. Then when you’re ready to use it you’ll go ahead and put it through a
strainer and then into the sprayer. It does a very good job of controlling
diseases. Now hydrogen peroxide, that’s something
else that you might find in the house. You will find in the house. It is usually
used for a little scratch that you get but it plays a lot of roles in the
organic garden. And so it is a very good disease fighter. When you spray it onto
the plant it begins to control any of the diseases before they get started. And that’s eight ounces to the gallon. That’s what that is. One of the things about using hydrogen
peroxide is you need to be very careful with it. More than that’s not better, as a matter
a fact it could burn the plants. So be conservative when you use
something like the hydrogen peroxide. When you follow the directions for these
different things you get the beneficial effects. Now I’ll bet you didn’t know that milk
is a great fungicide also. You can control your diseases easily by spraying the milk on there. And this about 1 cup of milk in nine cups water makes the spray. It prevents powdery mildew on your grapes, your squash, your melons. It’s a really good place to do this. And you can also use it undiluted to
clean your tools. making sure that the disease doesn’t
come along there. Alot of research was done on this and it was found to be more
effective than some other chemical controls.
There’s a few things that you might find in your kitchen that will give you excellent control of
some of the fungal diseases. Very safe and very effective. For
Backyard Basics, I’m John Dromgoole. I’ll see in the

    Thank you.John . Here a bulb of Garlic is $2.50 I rather eat it than spoil it, although I love my plants, perhaps I should use garlic powder. I don't have normal milk can I use coconut milk instead ?
